Biomarkers of mercury exposure at a mercury recycling facility in Ukraine Biomarkers of mercury exposure at a mercury recycling facility in Ukraine
This study evaluates biomarkers of occupational mercury exposure among workers at a mercury recycling operation in Gorlovka, Ukraine. The 29 study participants were divided into three occupational categories for analysis: (1) those who worked in the mercury recycling operation (Group A, n = 8), (2) those who worked at the facility but not in the yard where the recycling was done (Group B...

Transmission of atmospherically derived trace elements through an undeveloped, forested Maryland watershed Transmission of atmospherically derived trace elements through an undeveloped, forested Maryland watershed
The transmission of atmospherically derived trace elements (Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Se, and Zn) was evaluated in a small, undeveloped, forested watershed located in north-central Maryland. Atmospheric input was determined for wet-only and vegetative throughfall components. Annual throughfall fluxes were significantly enriched over incident precipitation for most elements...

Atmospheric wet deposition of trace elements to a suburban environment, Reston, Virginia, USA Atmospheric wet deposition of trace elements to a suburban environment, Reston, Virginia, USA
Wet deposition from a suburban area in Reston, Virginia was collected during 1998 and analyzed to assess the anion and trace-element concentrations and depositions. Suburban Reston, approximately 26 km west of Washington, DC, is densely populated and heavily developed. Wet deposition was collected bi-weekly in an automated collector using trace-element clean sampling and analytical...

Saxe and Beck (1) raise two groups of questions regarding the mass-balance approach in our paper. (i) Only some of the data and calculations used for the mass balance were provided; the apparent number of samples collected is not sufficient to support a reliable mass balance; measurements were not made on all tributaries.

Anthropogenic sources of arsenic and copper to sediments in a suburban lake, Northern Virginia Anthropogenic sources of arsenic and copper to sediments in a suburban lake, Northern Virginia
Mass balances of total arsenic and copper for a suburban lake in densely populated northern Virginia were calculated using data collected during 1998. Mass-balance terms were precipitation; stream inflow, including road runoff; stream outflow; and contributions from leaching of pressure-treated lumber. More mass of arsenic and copper was input to the lake than was output; the 1998 lake...

Water-quality data collected at Lake Anne, Reston, Virginia, 1997-1999 Water-quality data collected at Lake Anne, Reston, Virginia, 1997-1999
Samples from the Lake Anne watershed were collected and analyzed to assess the water quality from December 1997 through January 1999. Lake Anne is a stream impoundment in suburban Northern Virginia and its outflow is a sub-tributary of the Potomac River. Samples of wet deposition (precipitation), lake water, and streamwater that drain into and from Lake Anne were collected and analyzed...
